Why did the customer contact us?
The customer needed basement insulation.
Solutions provided:
High moisture content in CMU walls, 25-40%, Drywall approximately 15-22%. Moisture drive is due to high vapor pressure in soil and heavy vapor diffusion.
No water seen entering basement. To address these issues and stop vapor drive into basement the following is proposed: Customer will have contractor remove all firring strips, studs and drywall from exterior walls and ceiling prior to work being performed. Create a thermal break by installing Thermax foam board to all exterior walls from floor to ceiling. Seal and tape all seams.
To stop air flow into basement from floor apply 2 inches of closed cell foam to perimeter rim joist.
